“In school” vs “at school”
I've been writing some rules for an NLP recently, and I've come across a small problem... What is the difference in the use of "in" and "at". For example, you could say "I am in Hawaii right now", however you would (most likely) not say "I am at Hawaii right now".
You might say "I am in school right now" (implying that you are physically within the boundaries of "school"), but you might also say "I am at school right now" (meaning that you could be within school, next to school, or at the concept of school).
Any ideas for what the differences between the two are?
